It looks to me that the digital test just makes the situation worse by potentially giving a false negative due to the sensitivity threshold. In many cases being pregnant and not knowing it is worse than the converse. So the false positive may be better than a false negative. The "analog" version is capable of displaying a value marginally above 0 and lets your eyes and brain decide or at least raise a flag. The digital test replaces your eyes with crappy photodiodes, and your (even 16 year old) brain with a crappy controller that just looks at a high threshold and decides "below=0". I see people here saying that a digital is better because it reduces confusion. But it does so by discarding data. I'd take the debatable test every time, especially when for the money a digital one costs you can get multiple paper tests to do repeated checks.
